PotentialEnergyKineticEnergyTimeDifferencesbetweenWe present here a model that explains in a simple, easy and summarized manner, the values, meaning and reasons for the force of gravity, using simple physical tools. According to this model, a gravitational field actually creates different energy levels...
difficult one. We attempt to discuss gravitation from another angle in this work. Based on experimental analysis and theoretical verification, a hypothesis regarding mass in gravitational fields is presented. It can avoid the problem of singularity, and the meaning of gravitation is simple to ...
Indeed, should r0 be able to reach the UCO radius rUCO, then the deflection angle would diverge, meaning that the photon would turn indefinitely around the EiBI black hole, again, in absence of any perturbation. These light rays passing close to the UCO radius give rise to multiple images ...
Wide-field imaging and spectroscopic surveys are now available across various wavelengths, meaning that all-sky classification and cataloguing of galaxies and quasars is possible down to a few arcseconds resolution. Simple queries and self-cross-matches within these catalogues can be used to look for...
(As usual, the energy–momentum tensor is defined by 𝑇𝜇𝜈=−2−𝑔√𝛿𝑆𝑤𝑙𝛿𝑔𝜇𝜈.) The effective potential derived here is manifestly symmetric under 1↔2, as this construction is tailored for determining the conservative dynamics. The natural choice for the Green...
Hoffmann your kind assistance in translation." In the end, Einstein became convinced of the existence of gravitational waves, whereas Nathan Rosen always thought that they were just a formal mathematical construct with no real physical meaning. 3. Pirani's Trip to Poland; the Effect of a ...
Hydrostatic balance is the first manifestation of the gravitational potential energy in fluid systems. It reflects the fact that the pressure at any point in a static fluid is determined by the weight of the fluid above it. In this chapter we give a general thermodynamic derivation of hydrostatic...
The main gist of this video is that the universe we have now started with a "field" that was in all space (wherever that was) with a lot of potential energy associated with it. That field then expands by a factor of 10^27, so anything already in the field becomes so stretched that...
